If a woman who is a carrier for Tay-Sachs has children with a man who is not a Tay-Sachs carrier, what is the probability that one of their children will be a carrier for Tay-Sachs? (Sketch a Punnett square to help you find the correct answer.)   a. None   b. 25%   c. 50%   d. 75%   e. 100%

This is what I was tested on last week. All the information is already in the question. The professor gave me no other information. Is my professor wrong?

Joe's mother has Huntington's disease, which is caused by an autosomal dominant allele of the Huntington's gene (she has a heterozygous genotype). His father does not have the disease. The odds of Joe inheriting the disorder are: Select one: O a. 1 in 2 (50%) b. 3 in 4 (75%) One (100%) O d. 1 in 4 (25%)

Another blood disease, hemophilia, is caused by the failure of blood to clot.  The genetic basis for the disease is due to one of two dysfunctional clotting factor genes, recessive alleles that lead to the disorders hemophilia A and hemophilia B. Due to the long history of arranged European royal marriages within a relatively small sample population, the prevalence of both hemophilia and G6PD-deficiency disorder are both high. In fact, in certain family lines sons, but not daughters, are nearly always either born with both G6PD-deficiency and hemophilia A-disease or are born completely healthy. In other family lines sons, but not daughters, are born about a quarter of the time with both G6PD-deficiency and hemophilia B. (G = G6PD gene, A = Hemophilia A, and B = Hemophilia B, X = X chromosome, Y = Y chromosome) Which of the following arrangement of loci on chromosomes best explains these observations?  A B C D or E

Blood types in humans are Codominant. a. What are the possible genotypes of someone with type O blood? b. What are the possible genotypes of someone with type B blood? c. What is the phenotype of someone’s whose genotype is AO? d. A man with AB blood is married to a woman with AB blood. What blood types will their children be and in what proportion?

Pompe disease is a glycogen storage disorder caused by a lack of ⍺-glucosidase, the enzyme that converts glycogen to glucose in the muscles. Babies born with this disorder die by the age of two. pope disease is a genetic disorder caused by the presence of two recessive autosomal alleles. A. A man and a woman heterozygous for the condition have two female unaffected children. Determine, using a Punnett square, the probability, expressed as a whole number percentage, of a fourth baby being born a male with Pompe disease. B. Iftheman,fromthepreviousquestion,hadtypeAbloodandthewomanhadtypeO blood, what would be probability of them having a daughter with type O blood and affected with Pompe disease? (Show clearly your calculations and express your answer as a frequency between 0 - 1 and rounded to 2 decimal places)
